Pentax PF-CA35 overview

  • 1Description

Designed and built specifically for their 65mm, 80mm, and 100mm spotting scopes, the Pentax PF-CA35 K-Mount Digiscoping Camera Adapter allows you to quickly and easily mount your fixed f/12.5 aperture SLR or DSLR camera body onto the spotter to capture images of the Moon, birds, nature, or any subject that catches your eye. The snout simply installs in-place of the spotting scope's eyepiece, and your camera body attaches to the adapter using the same bayonet K-mount as your lenses.

    Pentax PF-CA35 reviews

    PF-CA35 K-Mount Digiscoping Camera Adapter is rated 3.8 out of 5 by 5.
    Rated 4 out of 5 by from Maybe I Was Too Harsh in My Earlier Review After doing more comparisons, I conclude that my earlier review was somewhat unfair to the product. I have been spoiled by my (both purchased used) Pentax A*300/2.8 and FA*300/4.5, so, by comparison, the adapter fell short of my expectations. However, the adapter, new, cost far less than either of the lenses did used. Today, I compared the adapter-scope combination with a Pentax K500/4.5 with 1.4x Rear Converter A (700mm equivalent), and the adapter results were at least as good as the lens-converter combination. Sooo, I conclude that the adapter was a worthwhile purchase and not bad at all, all things considered. But, it's not likely to give you Pentax *lens quality.

    Rated 5 out of 5 by from Sharp optics! At 1530mm focal length this is a must have accessory for any serious birder. I have just used this product to get photographic proof of an out-of-range bird in the Cape, South Africa. Without it I would never have been able to get close enough to the bird! Not only did I manage to get the image but the quality of the picture was so good you can count the hooks on the feathers!

    Rated 2 out of 5 by from Early results...cannot get dust out of the darned thing! This arrived about a week ago, and I finally got a chance to use it on my Pentax spotting scope with a K-to-E adapter and a Sony A7SII. Just practice shots, but found that there were a lot of spots in the two images I shot. Disassembled and tried different parts of the light path. Spotting scope does not have the spots. Camera doesn't through other optics. Looked inside this adapter, and was astonished at how dusty iit was inside. Have worked for a while on getting the elements cleaned, but the way they're recessed inside the tubing makes it pretty tough. And I still haven't gotten the four most prominent spots out of images, and am starting to wonder if the problem is inside. This may have to go back.

    Rated 5 out of 5 by from Works Great with Canon EOS with K to EOS I use this with a PhotoDiox K to EOS adapter with my Canon 7D body. Equivalent focal length 1500mm at F12. Good fit and good sharp flat field images.

    Rated 3 out of 5 by from Maybe It's Just Me, But ... This is a well-built item, but I wish I hadn't purchased it, especially given my experience with the Bushnell Spacemaster II and its camera adapter with the 15-power eyepiece, which simply never produced a sharp image for me. I figured that the PF-CA35, being a lens dedicated for photogaphy through the scope, might be better. It seems well-built, but, for the life of me I cannot get sharp images from it, except at the near-focus limit, and even those are blown away by the same image from real telephoto lenses. All the tripod bracing, mirror-lock-up, remote release, careful focusing, even using a properly adjusted Pentax 2x viewfinder magnifier (Ref Convertor A) and extremely high (>1/1000) shutter speeds make no difference. The pictures are soft, soft, soft, and this gets worse with increasing distance. The scope combination is hard to focus, even given the very smooth and precise focusing mechanism of the PF-80ED scope (which is a marvel), much harder than with a 300/2.8 and doubler (this should have been a clue from the beginning, but I'm stubborn to the point of stupidity). And yes, I've adjusted the viewfinder diopter. At 400 yards, the lettering on a dumpster is just plain fuzzy, yet, the same subject practicaly jumps off the screen with the 600 (doubler on the 300/2.8). The difference is clear even in the viewfinder. In short, the scope/adapter combination is good enough to tell one bird from another in good light, but is not even close to the sharpness I want for prints, a sharpness I get with an actual telephoto lens. Live and learn.
